Strap for Master Collection Date 36 Two Tone Stick

The lug width of the Longines Master Collection L2.518.5.12.7 is 19 mm. This measurement, also called lug width, should be verified precisely using a digital calliper positioned between the internal lugs of the case. It is essential to confirm this dimension before purchasing an aftermarket strap to ensure a perfect fit.

The optimal choice depends on intended use and personal preference. For formal occasions, opaque black alligator enhances the watch's dignity. For daily wear, cognac-toned calf or burgundy shell cordovan offer elegance and durability. A high-quality rubber textile strap permits informal versatility. Your choice should consider the chromatic contrast between the yellow gold and stainless steel case.

Remove the spring bars connecting the strap ends to the case lugs using a dedicated spring bar tool. Depress the pin and slide it out. Align the new strap holes with the lugs and insert the spring bar, ensuring it locks securely. Verify the strap is firmly attached before wearing the watch.

All straps with 19 mm lug width are compatible with the Master Collection L2.518.5.12.7. Milanostraps.it offers a complete collection of 19 mm straps in leather, rubber and fabric, customisable in size, colour and stitching thread. The Casati Milano atelier also creates bespoke straps with direct leather selection and 18-month warranty.

Longevity depends on material quality and usage patterns. Artisanal alligator with vegetable tanning lasts 5–8 years with ordinary care. Shell cordovan, owing to its density, often exceeds 10 years. Standard calf typically lasts 3–5 years. Regular maintenance—avoiding prolonged moisture and applying appropriate conditioners—significantly extends strap lifespan.
